10 bers rigidly connected to each other in a.

triangular relation, and the belt carrying frame in some cases has been rigidly connected to the su porting frame and in other instances givota ly connected to such frame,

the belt-carrying frame having been accomplished in the former instance by vertically frame adjusting'one end of the supplortin d ereo an m with respect to the other end t so the latter instance by swinging the belt-carng frame about its pivotal connectionwith t e supporting frame.

This invent on may be consideredas an improvement upon the above mentioned forms as of conveyers, and its object is to prov de a generally improved structure which W111 be simple in construction and reliable in use.

Other objects and advantages of the invention will become apparent from the .following description when taken in connection with the accompanying drawings in which' Figure 1 is a plan view of a conveyer embodying this invention; Figure 2 is a view showing the conveyer in side elevation; Figure 3 is a fragmental view in elevation showing in full lines and dotted lines respectively, the relation of the sup orting frame to the belt-carrying frame w an the latteris ad justed to upper and lower positions; and

Figure 4 is a transverse sectional view taken on line of Figure 3 but showing the beltcarrying frame adjusted to a position intermediate its upper and lower positions.

Referring to the drawings the numeral 5 indicates a supporting frame, provided with road wheels 6 and a belt-carryingframe 7 which may be provided with the usual form of endless belt, not shown, adapted to be supported with respect to the frame .7 on suit- 160 able transverse shafts 8 and 9 and driven by Y The supporting frame 5 includes, a pair 0 justment of the delivery end of a suitable power plant, such as a motor 10', operatively connected to the shaft 9 through the instrumentality of sprocket chains 11 and 12. Y

frameunits or side frames arranged at opposite sides of the belt-carrying frame 7, the I frame 'units being connected to an axle 13 upon which the road wheels 6 are mounted. Each of the side frames comprises a horizontally disposed frame member 14 and an. u wardly projecting frame member 15. The frame members14 and 15 are preferably in the form'of sections of pipe and by reason of such, the connections between the frame members 14 and 15 and the (axle 13 may be readily made by means of T couplings 17 and 18 respectively. The 'connections between the framemembers '14. and the axle 13 are rigid but the connections between the frame members 15 and the axle 13 are pivotal so as to permit relative movement between the side members 14 and 15, respectively, as and for the purpose hereinafter set forth. The side members 14 are pivotally connected to the belt-carrying frame, as shown at 19, so as to permit relative movement between the belt carrying frame 7 and the frame members 14' when. it is desired to adjust the delivery end of the conveyer to different positions to meet varying conditions of operation.

A sliding connection is provided between the belt-carrying frame 7 and the frame members 15, such connection being afforded by means of a transverse tubular shaft 21 which is journaled for slight rotation in side plates 22 carried by the frame 7'andis provided at its outer en with T-couplings23 adapted to slide upon the frame members 15 as the frame 7 is moved vertically to its adjusted positions. 1 he frame members 15 are connected'together at their upper ends by a transverse frame member 24, preferably in the form of a section of pi e, carrying at its outer ends suitable pipe ttings 25 which are secured to the upper ends of the frame members 15. Upon I the frame member 24 are journaled pairs 10f, pulleys 26, 26' and 27, 27 over which pass cables 28 and 29. These cables 28 and 29 are suitably connected to drums 30 of a winch mechanism 31, carried b the frame 7, and pass therefrom under pu leys 32 and 33, respectively, journaled upon the axle 13 from which pulleys they extend upwardly over the pulleys 26 and 27, thereafter .passing downwardly over ulleys 35 and 36 j ournaled upon the shaft 21 rom which they extend upwardly over pulleys 26' and 27 and downwardly to the shaft 21 to which their ends are anchored as shown at 37 and 38.

Assuming that the belt-carrying frame 7 is in its dotted line position shown in Figure 3 and it is desired to move such frame to its full line position shown in Figure 3, the winchviewed in Figure 3, due to the fact that the.

belt-carrying frame is pivotally connected to the frame members 14 at a fixed point. Since the shaft 21 is slidingly connected to the side members 15, such side members are forced to move from their dotted line position shown in Figure 3 toward their full line position shown in Figure 3 and as the side members 15 so move the shaft 21 is forced to move slightly about its axis. To lowerthe belt-carrying frame 7 from its elevated position, shown in full lines in Figure 3 to its dotted line position shown in Figure 3, the operation of the winch mechanism 31 is reversed, with the result that the belt-carrying frame 7 is permitted to descend by gravity, the downward movement of the belt-carrying frame being permittedby reason of the fact that the frame members 15 are pivotally connected to the axle' 13 and by reason of the fact that the shaft 21, which is slidably connected to the frame members 15, is rotatably connected to the belt-carrying frame 7.

The winch mechanism 31 is of the nonreversing type andserves, together with its associated parts, not only as means for raising and lowering the conveyer frame 7 but also as a means for maintaining that frame in various adjusted positions, as will be readily understood. Although the raising and lowering means for the conveyer frame 7 may serve to retain the conveyer frame in various adjusted positions, other retaining means may be employed as, for example, a pair of pins, one of which is indicated at 40 in Figure 3. These pins are adapted to be inserted in openings provided in the frame members 15 after the conveyer frame has been elevated to a desired position, whereupon the winch mechanism is reversed to permit the couplings 23 to move down into engagemgpt with the pins 40 and thus: allow the cables 29 to become slack. In order toadjust the conveyer frame 7 to a lower position, it may be first slightly elevated by the winch mechawardly by gravity as the cables 29 are unwound from the winch mechanism.

By thestructure embodying this invention, the belt-carrying frame 7 is utilized as a frame member in each of the side frame units and forms with the frame members 14 and 15, of each frame unit, a triangle in which that portion of the belt-carrying frame 7 intermediate its points of connection with the side members 14 and 15 forms a side. By reason of the fact that the belt-carrying frame 7 is so connected to the side members 14 and 15 as to form therewith a side of a triangle, strength and rigidity are afforded the side frame units des ite the fact that the belt carrying frame? is pivotally connected to the frame members. 14 and 15 and further despite the fact that the frame members 14 and 15 are pivotally connected to each other.

What is claimed is: 1. In a conveyer, an axle, side frames each including a lower frame member and an upper frame member connected to said axle for relative pivotal movement, a transverse frame member connectingsaid upper frame mem- ;bers together, a transverse shaft slidably connected at its ends to said upper frame ported by said conveyerframe for actuating said cables, whereby said conveyer frame may be moved about its pivotal connection with said lower frame members.

2. In a conveyer, an axle, side frames each including a lower frame member and an upper frame member connected to said axle for relative pivotal movement, a conveyer frame pivotally connected to the lower frame member of each side frame and including side plates,a transverse shaft located between said upper frame members, T-couplings carried at the opposite ends of said transverse shaft and slidableon said upper frame members intermediate their respective ends, said shaft being journaled in said side plates, a trans verse frame member connecting said upper frame members together, pulleys carried by said transverse frame member, pulleys carried by said axle, cables passing around the pulleys carried by said axle and over the pulle s carried by said transverse frame mem er and connected to said conveyer frame, and a winch mechanism for actuating said cables, whereby said conveyer frame ma. be moved about its pivotal connection with said lower frame members. i

In testimon whereof, I have afiixed my signature to t is specification.
